The invention relates to a special antenna for cable running state inspection equipment, which comprises a non-metal shell, a magnetic shielding layer, a limiting spring and a plurality of antenna units, the magnetic shielding layer is arranged on the inner side of the non-metal shell, the antenna units are arranged on the inner side of the magnetic shielding layer, and the antenna units are uniformly distributed in the circumferential direction. And the limiting spring is arranged between the antenna unit and the non-metal shell. According to the invention, electromagnetic induction detection can be directly carried out on any cable on a construction site, the whole antenna is rotated during use, the three groups of matrix antennas measure power frequency magnetic field signals at any position around the cable, the signals are sent to a host through a signal line, and the operation state of the cable can be accurately judged. 本发明涉及一种电缆运行状态检查设备专用天线，包括非金属外壳、磁屏蔽层、限位弹簧、天线单元，所述磁屏蔽层设置在非金属外壳的内侧，所述天线单元在磁屏蔽层的里侧，所述天线单
